When this
breakdown happens, the immune system responds by releasing
products that cause an inflammatory
reaction, activating abnormal clotting in the mother's lungs and blood vessels that can result in a serious blood - clotting disorder known as disseminated intravascular coagulation.
This saturation effect is due to negative feedback at high temperatures from chemical decomposition (molecules hitting so hard they break up) or a reversed
reaction process where the
breakdown of the
reaction products at high temperature cancels out the enhancement in production rate by temperature, and it is similar to the negative feedback from H2O on the effect of CO2 injections, see for example Figure 6 in http://vixra.org/pdf/1302.0044v2.pdf.
